MACHINE FOR FRAYlNG' GOODS.

SPECIFICATION forming part of Letters Patent No. 771,130, dated September 27, 1904.

Application filed February 5, 1904. Serial No. 192,185. \No model.)

To (all whom it may concern.-

Be it known that I, JAMES M. DEEN, a citizen of the'United States, residing at Harlan, in the county of Shelby and State of Iowa, have invented certainnew and useful Improvements in Machines for Fraying Goods, of which the following is a specification.

In the manufacture of goods having a pile or nap on the surface such as rugs, robes, and the likefrom carpets and like textile fabrics cut into strips and having their edges frayed the mode of preparing or fraying the edges of the textile strips is necessarily slow and costly, because of the treatment of each strip separately.

This invention aims to materially reduce the cost of manufacture of the class of goods aforesaid by providing a machine of novel formation which will at one operation fray the edges of a pile of strips in about the same time heretofore required to fray the edges of a single strip.

The invention consists of a channel adapted to receive a pile of textile strips and of a width corresponding to the width of said strips to prevent lateral movement thereof, a series of knives or cutters projected into the said channel from the walls thereof to slit the edges of the goods to provide the elements or fibers which form the nap, pile, or villous surface of the goods resulting from weaving said frayed or slitted strips in the accustomed manner, said knives or cutters having a clear space between their innermost extremities to prevent complete transverse severance of the strips and leave a longitudinalportion of Suflicient strength for handling'of the strips and durability of the tufted or villous goods woven therefrom and a follower for forcing the pile of strips through the channel and across the path of the knives or cutters whereby the edges of the strips are slitted, frayed, or fringed, so

' as to produce the nap, tuft, or villous elements.

tures of the invention are susceptible of modification, still the preferred embodiment of the invention. is illustrated in the accompanying drawings, in which Figure 1 is a side elevation of a machine embodying the invention. Fig. 2 is a top plan view thereof. Fig. 3 is a vertical longitudinal section thereof on the line X X of Fig. 2, showing different positions of the follower by full and dotted lines. Fig. 4c is a vertical transverse section on the line Y Y of Fig. 1. Fig. 5 is a plan view of a textile strip having its edge portions frayed or slitted to provide the nap or pile elements.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The channel is indicated at 1 and comprises the space formed between parallel walls 2, which may be of any length and depth, according to the capacity of the machine. Flanges 3 project outward from the walls 2 and constitute tracks for rollers 4 to travel upon in the operation of the follower. A series of knives or cutters 5 extend into the channel from the walls 2 and are spaced apart ashort distance, so as to effectively perform the work of fraying or slitting, so as to provide the fibers or elements constituting the pile, nap, or villous surface of the goods when the rug, robe, or other fabric is woven. The knives or cut ters 5 are fitted into grooves or seats 6, formed in the walls 2, and are disposed in parallel lines and in the same plane, so as to operate simultaneously upon the strips. The inner ends or extremities of the opposing series of cutters or blades are spaced apart, as indicated at 7, a distance corresponding to the portion of the strip to remain uncut or frayed and whiohis essential to admit of handling the strips in the operation of weaving and to provide the neces-e sary strength of goods when woven. Ol

viously if the strips are to be frayed or slitted upon one edge only one set of knives or cutters will be dispensed with; but inasmuch as it is usual and preferable to have both surfaces of the goods napped or provided with a pile both edges of the strips are frayed, hence the provision of two sets of cutters or knives, the

same serving also to support the pile at both sides, thereby insuring uniform fraying or slitting of both edges of the strips.

Any suitable means or presser device may be provided for forcing the pile of strips downward through the channel and past the knives or cutters; but the best results are attained by the use of the rocker 8, which enables concentrating the pressure at every point in the length of the pile of strips in the operation of the machine whereby a minimum amount-of power is required to be expended at any moment in the movement of the rocker throughout the length of the channel. The rocker 8 constitutes the follower, and its circumferential length corresponds to the distance between the extremities of the channel, so that a rocking movement will carry the follower from one end of the machine to the other, as indicated by the dotted lines in Fig. 3, and force the pile of strips through the channel and by the cutters. Arms 9 are located at opposite sides of the follower and are pivotally connected thereto at their upper ends by means of the bolt or pivot fastening 10 and are outwardly flared at their lower ends, which are provided upon their inner sides with rollers 4, mounted upon bolts or journals 11. i A handle 12 is secured to the rocker and is of sufficient length to provide ample leverage to facilitate the operation of the rocker when exerting pressure to force the pile of strips past the cutters. To equalize the strain upon the rocker, the lower end of the handle 12 is forked and embraces opposite sides of the rocker, as indicated most clearly in Fig. 4. The rocker is of segment form and is cut away upon each side of the handle 12 to provide points 13, which are adapted to engage over the ends of the channel and support the rocker when placing the pile of strips in the channel, as indicated most clearly at the left hand of Fig. 3. The walls 2 and flanges 3 are preferably of integral formation and are placed in parallel relation and connected at their ends by plates let, which are bolted or otherwise connected thereto, so as to admit of the parts being accessible when required for any purpose. Legs 15 support the body of the machine a distance above the bed or other part to which it may be attached, so as to provide a space below the channel for removal of the strips when cut.

The strips cut from ingrain, brussels, or other varieties of carpets or textile fabrics are placed one upon the other to form a pile, as

indicated at 16 in Fig. 3, said pile being placed within the channel upon the inner ends of the cutters or knives 5, after which the follower is operated by being rocked and simultaneousl y moved across the machine, thereby forcing the pile of strips through the channel and past the knives, whereby the edges of said strips are slitted or frayed, so as to provide the tufting elements which constitute the nap,

pile, or villous surface of the goods when woven. The strip when finished presents the ap1' earance substantially as shown at 17 in Fig. 5 and constitutes a woof element in the goods woven from the prepared strips.

Having thus described the invention, what is claimed as new is- 1. In a machine for fraying or slitting the edges of a pile of textile strips, the combination of a channel for receiving the pile of strips, a series of knives or cutters extended into the channel from a wall thereof, and means for exerting a pressure upon the pile of strips to force them through the channel and past the cutters, substantially as set forth.
